Key takeaways
  • Under the Divorce Act, the court looks only at the child's best interests, with primary weight on the child's physical, emotional and psychological safety, security and well-being.
  • The law encourages a child to have as much time with each parent as is consistent with their best interests, but it is not a presumption of 50/50 time.
  • Which statute applies depends on whether a divorce action has started, and a Parenting After Separation course is generally required before you file.

When you separate, one of the first questions is who the children will live with and who will make decisions for them. Many parents use the word custody, but the law now talks about parenting time and decision-making responsibility.

This article explains, in general terms, how an Alberta court decides parenting arrangements if you and the other parent cannot agree. It covers the best interests test, the factors a judge weighs, and the practical steps that usually come first.

This article covers the law of Alberta.

Custody is now parenting time and decision-making

Under the Divorce Act, decision-making responsibility means the responsibility for making significant decisions about a child's well-being, and parenting time means the time a child spends in the care of a person. A parenting order is the order that sets these out.

Decision-making responsibility can go to one spouse, both spouses, or a non-spouse who is a party to the application, so it can be sole or joint and can even be divided by subject. Unless the court orders otherwise, the person who has parenting time makes day-to-day decisions during that time.

Which law applies to your family

If a divorce action has started, parenting is dealt with under the Divorce Act, and the Family Law Act cannot be used for a matter already decided under the Divorce Act. If you were not married, or no divorce has been started by you or the other guardian, you can apply under the Family Law Act as long as the child lives in Alberta.

In Alberta, the ability to make decisions about a child is tied to guardianship rather than parentage status, and in most cases a child's parents are also guardians. If guardians agree after separation, they can keep exercising their powers without a court order. If they disagree, either guardian can apply for a parenting order.

The best interests test and its factors

When making a parenting order or contact order under the Divorce Act, the court considers only the child's best interests. It must give primary consideration to the child's physical, emotional and psychological safety, security and well-being. Alberta guidance describes the same approach for guardians who cannot agree under the Family Law Act.

The Divorce Act lists factors the court weighs. They include:

Alberta guidance for Family Law Act cases likewise points to the child's care history, the child's views, the benefit of relationships with both parents or guardians, and any history of family violence.

Children's views, family violence and past conduct

The court considers the child's views and preferences, giving them due weight according to the child's age and maturity, unless they cannot be ascertained. The Act sets no age at which a child decides.

The court must consider family violence and its impact, including its nature, seriousness, frequency and timing, any pattern of coercive and controlling behaviour, whether the child was targeted or exposed, harm or risk of harm to the child, and steps taken to prevent further violence. By contrast, the court must not consider a person's past conduct unless it is relevant to their parenting time, decision-making responsibility or contact.

Is 50/50 the starting point?

No. The Divorce Act says a child should have as much time with each spouse as is consistent with the child's best interests, but this is a guiding principle subordinate to best interests, not a presumption of equal time. Where safety is a concern, such as family violence, the child's safety, security and well-being take priority.

What to do next

Frequently asked questions

At what age can a child choose which parent to live with in Alberta?

The Divorce Act sets no age at which a child decides. The court considers the child's views and preferences and gives them due weight according to the child's age and maturity, unless they cannot be ascertained.

Does Alberta presume equal parenting time?

No. The maximum contact principle is a guiding principle subordinate to the child's best interests, not a presumption of 50/50 time. It applies only to the extent it is consistent with the child's best interests.

Does the court consider what a parent did during the relationship?

The court must not consider past conduct unless it is relevant to the person's parenting time, decision-making responsibility or contact. Family violence is different, because the court must consider it and its impact on the child.

Do I have to take a course before going to court?

The Parenting After Separation course is required before filing a divorce application or Family Law Act application in the Court of King's Bench, and a judge can also direct you to take it. A person who cannot complete a mandatory requirement can file a request to waive or defer it in the Family Justice Strategy areas.
